Am^jour^Pharm.j  Progress  in  Pharmacy.  277 
Pharmacy  and  Chemistry  (Journal  American  Medical  Association, 
April  20, 1907,  page  1365)  states  that  this  substance,  said  to  contain 
49  per  cent,  of  phenol  and  5  I  per  cent,  of  camphor,  really  consists  of 
a  mixture  of  approximately  20  per  cent,  of  phenol  and  38  per  cent, 
of  camphor  with  an  inert  substance  that  proved  to  be  liquid  petro- 
latum. 
Campho-penique  powder  was  found  to  consist  chiefly  of  an  inor- 
ganic talcum-like  substance  with  approximately  8  per  cent,  of  a 
mixture  of  camphor  and  phenol,  chiefly  the  former. 
Medicinal  Foods. — The  Council  on  Pharmacy  and  Chemistry  of  the 
American  Medical  Association  has  recently  published  an  exhaustive 
study  on  the  comparative  value  of  so-called  medicinal  foods  and  milk. 
(Journal  American  Medical  Association,  May  n,  1907,  page  161 2.) 
This  report  is  too  exhaustive  and  in  many  respects  too  technical 
to  abstract.  It  should  be  carefully  studied  by  every  pharmacist 
who  is  at  all  interested  in  the  professional  side  of  his  calling,  so  that 
he  may  be  in  a  position  to  further  explain  the  various  points  in 
connection  with  it,  to  the  physicians  in  his  neighborhood. 
Glyco-Thymoline. — Dr.  J.  Kochs  (Apotheker  Zeitung,  1907,  page 
167)  reports  an  examination  of  this  preparation  made  in  the  Pharma- 
ceutical Institute  of  the  University  of  Berlin.  One  rather  interesting 
point  is  the  statement  that  the  mixture  is  now  colored  with  tincture 
of  cochineal.  In  other  respects  this  analysis  conforms  rather  closely 
to  others  that  have  been  made  in  this  country.  Dr.  Kochs  con- 
cludes that  the  preparation  consists  of  potassium  carbonate,  sodium 
benzoate,  sodium  borate,  smaller  portions  of  sodium  salicylate, 
thymol  and  menthol  with  glycerin  and  alcohol,  and  colored  with 
tincture  of  cochineal. 
Aniso-theobromin. — Theobromine  sodium  anisate  is  a  double  salt 
that  is  only  slightly  soluble  in  water.  It  is  claimed  to  have  the 
action  of  diuretin,  but  to  be  devoid  of  all  deleterious  action  on  the 
heart.    (Phar.  Zeifg,  1907,  page  280.) 
Atoxyl. — E.  Forneau  (Journal  de  Phar.  et  Chem.,  1907,  page  332) 
asserts  that  the  statement  made  by  the  manufacturers  of  atoxyl  that 
it  is  the  anilid  of  metarsenous  acid  is  not  correct  and  that  it  in  reality 
is  the  mono  sodium  salt  of  ortho  arsenic  acid.  Atoxyl  does  not 
contain  37-69  of  arsenic,  as  claimed,  but  only  29  per  cent.  It  is 
further  stated  to  be  identical  with  a  preparation  made  by  Bechamp, 
in  1863,  by  heating  anilin  arseniate.
